✨ stm32f4_i2c_isr_event ✨

okay so bestie, welcome to the Kernel API Manual — this lil page is all about stm32f4_i2c_isr_event, aka the Interrupt routine for I2C bus event 💅 like, literally the function that handles the I2C bus event interrupt. no cap, that's the whole vibe.

🎀 SYNOPSIS 🎀

irqreturn_t stm32f4_i2c_isr_event (int irq , void *data );

it's giving "one function, two args, returns an irqreturn_t" — periodt. copy it exactly, don't be out here renaming things 🙈

💖 ARGUMENTS 💖

• irq — the interrupt number 🩷 like, which interrupt are we even talking about, y'know? it's an int, it's the interrupt number, that's it, that's the whole personality.
• data — the Controller's private data 🦋 a void *, so it's mysterious and could be anything — but in this case it's the controller's own private data. main character energy honestly.
